Momentus Plans to Deploy a SteamJet Cubesat on Its Next Mission

Founded in 2017, SteamJet, a United Kingdom propulsion startup, builds water-fueled resistojet propulsion for small satellites and cubesats. SteamJet Space Systems is the most recent customer to sign up for Momentus' Vigoride space transportation service.

FREMONT, CA: Momentus announced its plans to deploy a SteamJet cubesat on its Vigoride demonstration mission, which is scheduled to launch later this year on a Russian Soyuz rocket. They announced this plan at the SmallSat Symposium on 4th February. Founded in 2017, SteamJet, a United Kingdom propulsion startup, builds water-fueled resistojet propulsion for small satellites and cubesats. SteamJet Space Systems is the most recent customer to sign up for Momentus' Vigoride space transportation service.

"It's a pleasure to be working with Momentus on launch integration and using their technology for our final orbital placement," SteamJet CEO Pavel Savin said in a statement. "Momentus has created a fantastic efficiency-to-cost ratio. We look forward to continuing the relationship with future SteamJet satellites."

The 1.5-unit cubesat of SteamJet will be integrated into a deployer designed to fit several cubesats built by Innovative Solutions in the space of the Netherlands. After integration, the deployer will then be mounted on Momentus' Vigoride transfer vehicle, Dawn Harms, Momentus chief revenue officer, said.

During orbit, SteamJet intends to display an impulsion system that uses water or another low pressure, non-corrosive, non-toxic fluid propellant to create thrust. SteamJet houses its propulsion system in a component shaped like a tuna can that attaches to the exterior of a cubesat.

Momentus has a total of five customers signed up for shuttle flights in the next two years i.e., 2020 and 2021. Five more customers, including Exolaunch and Deimos, have signed up for Momentus charter flights to destinations not served by shuttle flights.
